Because JKLM is a parallelogram, opposite sides are equal and = 7. Midpoint N divides
that 7 into two equal pieces of each. The area of the parallelogram, which is equal to the
base times the height, is given as 28, and because the base is 7, altitude = 4. Put all this
into the figure.Use the Pythagorean theorem to determine the length of .Now add all the sides of the parallelogram to find the perimeter: 7 + 7 + 5.3151 + 5.3151 =
24.6302.
